So many things that I wish that you knew.
If Allah brings you to it, He will bring you through it. In Happy moments, praise Allah. In Difficult moments, seek Allah. In Quiet moments, worship Allah. In Painful moments, trust Allah. In Every moment, thank Allah.
It takes time to understand a girl. But if she's really worth it, you'd take the time to try and figure her out. You can't know everything about a girl in a matter of days. It takes time. Phone calls, fights, dates, and every minute you're with her, you begin to know more and more about her. It takes time to know a girl well. Not fully, but well. If she really mattered to you, you'd take the time.
